Too remove or not remove rubbery floor glue?
 

Hi,

Just peeled some more old flooring up in the bungalow. It had been stuck
down with what looks like industrial evo-stick. The flooring cleaved off
with a spade, but there remains a layer a mm or two thick of the rubbery
adhesive.

Seems stable - stable enough that a spade won't touch it.

My inclination is to stick my insulation board straight to this - I'll be
using a cementous tile adhesive to do this.

Now, ideally (and according to the adhesive manufacturer) I should remove
the rubber gunk. But quite frankly, given it's in the surface of the
screed, it would need either a million gallons of petrol, a mega scrabbling
machine or semtex.

Has anyone any bad experiences of tiling straight over this sort of stuff?

Cheers

Tim

PS

Stripped the last room of wallpaper today and removed the old bog and basin
upstairs. Need to wash down two ceilings, clear a load of manky glass wool
and some plasterboard upstairs, then I'm ready for some serious
reconstruction. Photos will come. Had another bay window ceiling off and
pleased to say, not rot, despite evidence of previous leaks.

PPS Getting ready to install new CU. Got 5m of this in 32mm size:

and a bag of these:

to run the meter tails through. I have to take the tails out the side of the
meter box and up through the eaves, so I needed something tough and with
good ends to form a decent seal to the box.

Tough is an understatement - it's about 4mm thick plastic and the
terminations look like tank connectors. Only disadvantage is poor bend
radius, but I have a route for it that should work quite well. The route
doesn't demand "mechanical protection" in the IEE meaning of the phrase,
but this stuff does seem to offer pretty good general protection -
definately better than just dangling some tails though the roof space.

Yes, I went over it with a levelling screed, which gave me a smooth and
level surface to tile on to.

A shop fitters trick for killing off the stickyness of surfaces like
this is to sweep some dry levelling compound powder over it. It sets
into all the sticky bits and stabilises them.

Ah. I seem to have already achieved that with plaster dust :)

It was only the technical bloke from Mapei who said "scrape it off" that
made me think - but then, I suppose he'd have to say that.

The first Mapei bloke was a bit more helpful, in that he said (of sticking
Marmox to concrete with no DPM): "well, we can't guarantee it won't fall of
in 20-30 years due to hyrdostatic pressure - but KeraQuick's your best bet
of all our products". Simple advice with pros and cons - then I can make an
informed decision.

Ah yes - that stuff sticks to everything. It's an option.

It's probably just a coincidence but the levelling screed I use is from
Evo Stik. ;-)
